Mobile fracturing pump transport for hydraulic fracturing of subsurface geological formations

A fracturing pump transport comprising:

• a first fracturing pump comprising a first fluid end assembly;
• a second fracturing pump comprising a second fluid end assembly, wherein the first fluid end assembly and the second fluid end assembly face a same side of the fracturing pump transport;
• an electric motor comprising a shaft having a first end and a second end that axially extend on opposite sides of the electric motor;
• a first drive line assembly coupling the first fracturing pump to the first end of the shaft, wherein the first drive line assembly comprises a first engagement coupling that allows for selective engagement, disengagement, or both of the first fracturing pump with the first end of the shaft;
• and
• a second drive line assembly coupling the second fracturing pump to the second end of the shaft, wherein the second drive line assembly comprises a second engagement coupling that allows for selective engagement, disengagement, or both of the second fracturing pump with the second end of the shaft, wherein the first fracturing pump comprises a pinion shaft with a first pinion end and a second pinion end that protrudes on opposite sides of the fracturing pump.

A method for pumping and pressurizing fracturing fluid, the method comprising:

• receiving, at an electronic controller of an engagement panel, a disengagement command from a location remote to a fracturing pump transport;
• adjusting, using an electronic valve of the engagement panel and in response to receiving the disengagement command, a hydraulic fluid pressure to disengage a first fracturing pump mounted on the fracturing pump transport from an electric prime mover mounted on the fracturing pump transport;
• disengaging, in response to adjusting the hydraulic fluid pressure, the first fracturing pump from the electric prime mover using an engagement coupling, wherein the engagement coupling is part of a first drive line assembly that allows for selective engagement between the first fracturing pump and the electric prime mover;
• and
• driving a second fracturing pump mounted on the fracturing pump transport with the electric prime mover after disengaging the first fracturing pump from the electric prime mover using the first drive line assembly, wherein the first fracturing pump comprises a pinion shaft with a first pinion end and a second pinion end that protrudes on opposite sides of the fracturing pump.
